Hey guys, as I'm sure you know SCT is making Xcal 3's that have 3 preloaded tunes for the 3.9L LS now. Part #SCL-3015. Of course you can buy a blank Xcal3part # SCL-3000 and purchase the Torrie tunes for it. The price for the preloaded one is $379 and the blank one is $379 plus the cost of Torries tunes which I believe are $150. Have any of you had expierence with each? My car is pretty much stock, just a K&N intake and magnaflow cat back. I'm wondering if its worth getting the Torrie tunes or not. If they are better I'm willing to pay though. Let me know what you think. Thanks.
